The present iiiv'en'tioii mines to a spreading attachment andinore in" particular tosuch an attachment or blade adapted tote 'detaoh'albly mouhted' On'the E'i'id "Ur tELiPgateOf ai'iy s tihdalfd fidumping truck. I A

Among the objects of the present invention is toprevide a. novel spreading attachment adapted to be mounted on the tail or end gate or a truck or other Vehicle and which is adapted to evenly spread the material being dimi ed therefrom.

further object (if the invention is the provisien of a novel 'spre'aiding'device adapted to'b attached to the realr of a dumping body of a; truck or other vehicle and drawn along there"- to spread dirt, gravel", stone and7o'r other road material as it is discharged or dumped from the truck or Vehicle. V V

Astill furtheifl'ohjeot is the provision of a; novel spreeidi n'g attachment which may be easily and readily mounted on the end gkate" or at the reelr f the body of an standard dfilnp' tii'l'bk a'lidj qiii'dkifv detached therefrom whenever desired.

However, the attachment soconstrh'cted and mmmtee that it may be retained upon the body Of'th' truek altali'tirii'es Without meaning the operation or effici-en'cy of wish triick or other vet-hole. r

Another object of theinvention is to provide an evctj-iistabl e spreader attachment for dump 3o bodies, The spreading blade" may be adjusted through a: very wide range to permit spreading of dirt, gravel, stone; sand and/or other road material. the present disclosed embodiment, this a:d1istment permits the spreading of any desired thickness from one" inch to eighteen inches although it is to he understood the disclosedembodiment and range of adjustment is to be taken as illustrative only and. that numerone other ran-gesof aidjii'stment may be" provided. Yet another object of the invention is the ro: vision of a spreading attaohment which utm maitieail-w operated upona; raising" of the boeiy"*an'ici opening ofth'e tail or end gate. When the body islirw'er'ed. or retii rned to its normar or proper position, the blade or spreader is auto maitica liy' raised. to mopemtwe pos'itiofiwhereby the blade or spreader cl'ea'r's all'obstrliotior'is and.- inno way interferes with the norms-1 operation ofthe truck. r I

The dump" body is provided at its rear nd' with $61 enci gate 7 pivot-err u'p'oxi h nge 8;; This and gate forms a nonnar assure for'the' b'Ody WHf by to' prevent diSlTa'T-g'e of the contents of the duh p bbdy' 011' when it" is" in ai lb we rti of naming position and to perh'iit fre disohafg" of su'ch oonte'nts \ivl 'ieh the body' or tfnc kis an 'ei eva te'd po'sitioh'. aforementioned trfik construction may be any of the stnlird rrilis or mouth; I p I 0f the end gate 7 and pivo aiiy ett'aohed to the opposite si'cie'flttngs" 1o r end get-fleshy new of arm-f1;- bolt 01'" theme 11" seeping within as v openingm the bars 9: and 0Y10f 3; plume of openings 1T2" the flanges 10. These arms or' bars '9 ca-fiy'gstheirlbwer end a: transversely tending biade or spreading member 13- dapted to spreao'l the materiai discharged froth the dump" arms or bars 9 and are connected by a pin, bolt or the like 15 seating in one of a plurality of openings 16 in the bars or brace arms 17. The upper end of these bars or brace arms is pivotally connected to the flanges 10 of the end gate by means of a pin, bolt or the like 18.

By reason of the openings 12 in the flanges 10 of the end or tail gate and the openings 16 of the brace arms 17, it will be readily seen that the blade 13 may be raised or lowered to vary the depth of the material to be spread. Also, the blade may be tilted to different positions by adjusting the brace bars on the opposite sides of the end gate to different positions. This may be readily accomplished by reason of the numerous openings provided in these brace bars permitting such adjustment.

In order to limit the position of the blade or spreading member 13 and to hold it to its work, the invention comprehends the provision of a chainor other flexible member 19 adapted to be connected at 20 to the lower end of the arms or bars 9 and at their opposite ends to the bracket 21 mounted on the frame 6 of the truck. A grab hook or other suitable means 22 may be provided for connecting the chain to a loop 23 and for adjusting the length of such chain or flexible member.

The present novel construction of spreading attachment permits the emcient handling of dirt or other lumpy material and which would have a tendency to clog in structures in which there is a hopper arrangement. It is likewise admirably adapted for handling gravel, sand, stones or other road material. It may be adjusted to permit the spreading of any desired thickness, depending merely upon the number and range of openings in the flanges l0 and brace arms or rods 1'7. Upon a raising of the body, the tail or end gate opens by reason of its pivotal connection whereby to permit a discharge of the contents of the dump body. Upon opening of the tail or end gate, the attachment automatically operates to spread and level thematerial to the adjusted depth. When the dump body is lowered to its normal position, the tail or end gate closes the discharge opening of the truck and the bladeand attachment. is raised to a position whereby it will clear all obstacles or obstructions. Thus it may be retained in operative position without in any way interfering with the normal operation of the truck. However, if it is desired to remove the attachment, this may be done in a very few minutes, since it is only necessary to remove the several pins or bolts holding it in place.

The present novel construction may be readily and easily attached to any standard dump truck and quickly detached therefrom. When it is being operated, the weight and force of the material which is being dumped and positioned against the blade will maintain the blade in its proper position as the truck is being moved or propelled forward.

Having thus disclosed the invention, I claim:

9. A spreading attachment adapted to be mountedupon the body of a dump truck-comprising arm members connected to the end gate of said bodyand a spreading member adjustably mounted on said arm members and adapted to spread the material discharged through said end gate.

10. A spreading attachment adapted to be mounted upon the body of a dump truck, comprising a blade mounted on and depending from the end gate of the body and movable therewith whereby upon the opening of the end gate to discharge the contents of the body, the blade automatically assumes a position to spread and level said discharged contents, and when said end" gate is closed, the blade is retained in a position sufficiently above the ground as not to interfere with the normal operation of the truck.
